AM-1221 is a drug that acts as a potent and selective agonist for the cannabinoid receptor CB2, with a Ki of 0.28nM at CB2 and 52.3nM at the CB1 receptor, giving it around 180x selectivity for CB2.The 2-methyl and 6-nitro groups on the indole ring both tend to increase CB2 affinity while generally reducing affinity at CB1, explaining the high CB2 selectivity of AM-1221. However despite this relatively high selectivity for CB2, its CB1 affinity is still too strong to make it useful as a truly selective CB2 agonist, so the related compound AM-1241 is generally preferred for research purposes.
